It always surprised me that he didn't get pulled over more often when he was hauling it to our campouts.
I've made many of these little canons from old worn out rifle and pistol barrels seldom do I ever pack a wad with black powder and touch them off. Like I said before they are really just to sit on a shelf and be looked at ... I've been thinking about making a large smooth barrel replica to anchor into concrete in my front yard as yard art but I don't think I'll drill the fuse hole all the way through just so the police wont take issue ... on the otherhand it would be fun to take a working version out to the desert and throwing a few 6 pounders around ... uh ... maybe not.
